Review on Marineland Rite-Size C Cartridge, 12-Pack - Enhanced SEO by James Wing

I don't get it but on some occasions these pads must be broken now because I just replaced them and my filter is spilling to the side which means they run less through the pads. Maybe they are too tight? I also double them. Removing one does nothing. I use flush feed so overfeeding is not a problem. There is little dirt on the filters. Now, in other cases, they spend months filtering other buyers. Is it the same packaging? Guest!
